I think we might need to discuss about explicit version checks in pg_restore.
It is not related with large objects, but with pg_restore's capability.
We've not supported to restore a dump to older servers, but we don't have any
version checks, right? Should we do the checks at the beginning of restoring?
If we do so, LO patch could be more simplified.

I think large object metadata is a kind of row-based access controls.
How do we dump and restore ACLs per rows when we support them for
normal tables? We should treat LO metadata as same as row-based ACLs.
In my opinion, I'd like to treat them as part of data (not of schema).
